EPDM (Ethylene-Propylene-Diene-Monomer)

EPDM rubber is used in vibrators and seals; glass-run channel; radiator, garden and appliance hose; tubing; washers; belts; electrical insulation, and speaker cone surrounds. It is also used as a medium for water resistance in high-voltage polymeric cable jointing installations, roofing membrane, geomembranes, rubber mechanical goods, plastic impact modification, thermoplastic, vulcanizates, as a motor oil additive, pond liner, electrical cable-jointing, RV roofs, and chainmail applications.

The main properties of EPDM are its outstanding heat, ozone and weather resistance. The resistance to polar substances and steam are also good. It has excellent electrical properties. It has the ability to retain light colour.

Liquid Rubber is designed to recoat structurally sound existing roof and protective materials. They should not be used in place of roofing membranes”.

The following are recommended substrates to coat:

Metal – Coated or Galvanized Steel
- Weathered Aluminum
- Weathered Copper
EPDM Rubber membrane
Fish Ponds and Fountains (PondPro2000)
Concrete (except foot traffic surfaces)
Urethane Foam
Primed Wood
Fiberglass
DICOR- Liquid EPDM will adhere to Dicor caulk
Eternabond Tape- Liquid EPDM will adhere if the Eternabond is sanded lightly and primed with a light coat of contact cement
PVC Sheet and Pipe
Acrylic Sheet
Sponge Rubber insulation
Polystyrene
Polycarbonate
Wood if the roof is over a non-living area
Durolast; however, any seam problems should be repaired with the Butyl Tape.

Do Not use Liquid Roof or Liquid Rubber on the following substrates:

TPO
Built up asphalt roofs
Asphalt shingles
Modified asphalt roll roofing
Stainless steel
Glass
Silicone caulk
Foot traffic surfaces
Hypalon Membrane
BUR
Modified Asphalt
Hot Mop
Sprayed Polyurethane
Polypropylene

EPDM is a synthetic elastomer made by combining ethylene and propylene with a diene monomer attached. This polymer (when cross linked) is a very good moisture barrier, resistant to oxidation and UV degradation but its most important property is its ability to tolerate both low as well as high temperatures (form minus 62 to plus 350 degrees Fahrenheit). EPDM is excellent for both new construction and roof replacement. EPDM offers high tensile strength, extreme elongation capabilities, and is generally compatible with other materials used in most roofing applications.

EPDM Liquid Rubber and Rubber Roof has a long history of superior performance in hoses, molded products, roof leaks repair, tires and roofing membranes. For example, the radiator hoses in our cars and the gaskets on our freezer doors are made of EPDM rubber and show the broad temperature range the product can handle. EPDM Roofing Membranes also have more than 30 years of successful history. It is relatively inexpensive, simple to install, and fairly clean to work with when compared to conventional materials. There are not the strong odors and fumes either. The product is very stable and the resulting characteristics of Liquid EPDM and Liquid Roof Rubber such as flexibility, weather ability and chemical resistance are determined by it. Liquid EPDM therefore, can be described as a new form of an old and well-established rubber polymer. Now you can take advantage of the same benefits to weather-tight your leaks. Liquid EPDM forms a 100% seamless layer. No other product can match the durability of EPDM Liquid Roof Repair Products. EPDM roofs are suitable for most types of facilities, offer various mil thicknesses, and can be purchased in either black or white. It should be noted that the solar reflectivity of a black roof is only 8%, which is a major factor in the Sun Belt. EPDM Rubber also has the broadest temperature tolerance, and is not water-soluble even in the uncured state. Even if you happen to get a unexpected rain shower just after you applied Liquid EPDM there's no need to worry; Liquid EPDM will not wash off.

Liquid EPDM Rubber vs. Neoprene Rubber

Early in the flexible membrane market explosion, owners and contractors recognized EPDM roofing as a cleaner, cooler and generally easier product to handle than the built-up roof (hot tar or asphalt) to which they were accustomed. With very little capital investment, they were able to obtain all the tools and equipment needed to properly install a roof. These systems also offer low maintenance, easy repair options and low annualized cost. EPDM rubber was not available in liquid form until relatively recently so Liquid Neoprene rubber became the material of choice for protecting concrete Roof against both fresh and salt water. The Liquid Neoprene products are simple solvent solutions or water based emulsions and therefore has low solids content and relatively low molecular weights. These limitations made multiple coat applications necessary and required top coating with other polymers to prevent ultra violet degradation. Liquid Rubber also provide a strong solution for all type of roof leaks repair and Roof sealant repair. All type of metal roof, RV roof, commercial and residential roof leaks repair.

The development of Liquid Rubber resulted in a high solids, two components chemically reactive product capable of polymerizing at ambient temperatures 55 F (13 C) and higher. This product can be applied at a 30 mil dry film (.76 mm) in a single application because of the high solids content. Its chemical cure feature then results in a high molecular weight film with protective and performance properties exceeding those of liquid applied Neoprene films.

Advantages of EPDM

A little research turned up EPDM Coatings is a best choice for repairing roof leaks in flat roofs, concrete roofs, Metal Roofs & RV Roofs etc. Single-ply EPDM rubber roofing has many advantages over other roofing options. It remains flexible at extreme temperatures, can be installed quickly, and resists deterioration from exposure to ultraviolet radiation -- a protective coating, like natural stone, is not required as with some torch-down products.
Warranty. The 10-year EPDM Coatings warranty is, to date, the best I've found in the category of residential low-slope roofing products. And, if the performance of single-ply EPDM roofing on commercial installations is any measure, EPDM Coatings can certainly last much longer than 10 years, if it's properly installed. Granted, the product was a little hard to find for this job.
Temperature range. EPDM coatings are best installed at temperatures ranging between 40F and 80F. However, there is some latitude. If it's 35F, but it's sunny on the deck, the material may be workable enough. The same holds true if it's 85F but cloudy. The glue on the product gets very aggressive in high temperatures, and special techniques must be used to install it.

epdm liquid rubber Liquid Rubber can withstand boiling water or live steam and is inherently UV and ozone stable. The product is safer to use because of its higher flash point and the two component packaging permits extended storage at higher temperatures than liquid Neoprene. The non polar characteristic of the EPDM also gives it advantages over Neoprene in saltwater environments as well as better resistance to cathodic disbondment. Liquid rubber has poor resistance to oils, fats, waxes and aliphatic solvents but possesses very good resistance to ketone solvents, alcohol, polar compounds, Salts, most acids up to 50 % concentration, alkalies and water. Application of Liquid roof products And Rubber Roof Coatings.

Many times when a roof membrane starts to fail, there are only two options: do nothing and live with the leaks or tear the old roof off and replace it. EPDM coatings give you another option. Now you can coat your roof with EPDM on existing membrane and enjoy the benefits of reduced energy bills, a longer lasting roof, and the ability to apply the new membrane without major disruptions to your business. In addition, this system is completely sustainable meaning you can continue to recoat the acrylic coating, as needed, for years and years to come.
